In this article, a simple PHP class is implemented to list all the files in the specified directory in a weighted structure. Friends who are interested can take a look.
List all the files in the specified directory in a tree structure. In this way, all the files in the directory will be clearly structured in front of you. You can know what files there are at a glance, which is very convenient. Example, <? /** * 列出目录中所有文件 * by 程序员之家 bbs.it-home.org */ #例子 $t = new TreeClimber( "asp" ); //新建物件,设置需要列出的目录:在此为asp目录 echo arrayValuesToString( $t->getFileList( $t->getPath() ), "<BR>\n" ); function arrayValuesToString( $ar, $nl="", $dolast=true ) {//调用函数 $str = ""; reset( $ar ); $size = sizeof( $ar ); $i = 1; while( list( $k, $v ) = each( $ar ) ) { if ( $dolast == false ) { if ( $i < $size ) { $str .= $ar[$k].$nl; } else { $str .= $ar[$k]; } } else { $str .= $ar[$k].$nl; } $i++; } return $str; } //类 TreeClimber class TreeClimber { var $path; var $fileList = array(); function TreeClimber( $path = "." ) { $this->path = $path; } # 存取路径 function getPath() { return $this->path; } function setPath( $v ) { $this->path = $v; } // 返回指定目录里的文件列表,如果没有指定目录,将使用当前目录 //如果不能打开目录(可能没权限或目录不存在,将返回为空 //以递归方式进行 function getFileList( $dirname=null, $returnDirs=false, $reset=true ) { if ( $dirname == null ) { $dirname = $this->path; } # else { $this->setPath( $dirname ); } # dout( "Recursing into $dirname..." ); if ( $reset ) { $this->fileList = array(); } $dir = opendir( $dirname ); if ( ! $dir ) { print( "<B><FONT COLOR=#FF0000>注意: TreeClimber.getFileList( $dirname ): 不能打开 $dirname!</FONT></B>" ); return null; } while( $file = readdir( $dir ) ) { if ( ereg( "^\.$", $file ) || ereg( "^\.\.$", $file ) ) continue; if ( is_dir( $dirname."/".$file ) ) { $this->getFileList( $dirname."/".$file, $returnDirs, false ); if ( $returnDirs ) { $this->fileList[] = $dirname."/".$file;} } else { $this->fileList[] = $dirname."/".$file; } } sort( $this->fileList ); return $this->fileList; } } ?>When you use the above PHP class, remember to test it in a directory with fewer files first to get a clear tree structure. Of course, you can also extend this class to achieve more powerful functions. |
